BACKGROUND 1. Technical Field

The present disclosure relates to a semiconductor packaging process, andmore particularly, to an electronic package capable of supplying powerand a manufacturing method thereof.

2. Description of Related Art

In order to ensure the continuing miniaturization andmulti-functionalities of electronic products and communicationequipment, semiconductor packages need to be downscaled to facilitatethe connections of multiple pins as well as high speed operations andhigh functionalities. For example, in advanced process packaging, thecommon types of packaging include 2.5D packaging process, Fan-OutEmbedded Bridge (FO-EB), etc. Compared to 2.5D packaging process, FO-EBhas the advantages of lower costs and a greater number of materialsuppliers.

FIG. 1-1 is a cross-sectional schematic view of a semiconductor package1 of a conventional FO-EB. The semiconductor package 1 includes a firstsemiconductor chip 11 and a plurality of conductive pillars 13 disposedon a substrate structure 10 having a circuit layer 101. The firstsemiconductor chip 11 and the conductive pillars 13 are then covered byan encapsulant 15. A routing structure 16 that is electrically connectedto the first semiconductor chip 11 and the conductive pillars 13 is thenformed on the encapsulant 15. A plurality of second semiconductor chips14 electrically connected to the routing structure 16 are disposed onthe routing structure 16. The second semiconductor chips 14 are thenencapsulated by an encapsulation layer 18, wherein the circuit layer 101and the routing structure 16 adopt the standard for a fan-outredistribution layer (RDL). The first semiconductor chip 11 acts as abridge component embedded in the encapsulant 15 for electricallybridging two adjacent second semiconductor chips 14.

In the conventional semiconductor package 1, the substrate structure 10is disposed onto a circuit board 1 a via a plurality of solder balls 12,and the conductive pillars 13 are electrically connected with thecircuit layer 101, wherein some of the conductive pillars 13 can be usedin conjunction with the circuit layer 101 and the routing structure 16as an electrical transmission structure, such that power required by thesecond semiconductor chips 14 that are distant from the circuit board 1a can be provided by the circuit board 1 a through the circuit layer 101and the conductive pillars 13.

However, in the conventional semiconductor package 1, for electroniccomponents positioned above the routing structure 16, the closer theelectronic components are to the center of the first semiconductor chip11, the greater the direct current (DC) resistance created, and poorerthe ability for supplying power. In other words, power transmissionpaths are too long, such that the impedance is increased (such as animpedance curve L2 shown in FIG. 2F-1). As a result, some of electroniccomponents above the routing structure 16 may not have enough power oreven have power outages. For example, for a second semiconductor chip 14on the right-hand side of and above the routing structure 16, a powersupply contact 17 of the second semiconductor chip 14 is positioned ontop of a contact 110 at the center of the first semiconductor chip 11.Power has to be transmitted from a power supply port of the circuitboard 1 a to the power supply contact 17 via the circuit layer 101, aconductive pillar 13 on the right-hand side of FIG. 1-1, and the routingstructure 16. This power transmission path is very long, creating alarge impedance that increases the likelihood of power outages for thesecond semiconductor chip 14 on the right-hand side of and above therouting structure 16.

Therefore, there is a need for a solution that addresses theaforementioned issues of the prior art.

FIGS. 2A to 2E-1 are schematic cross-sectional views illustrating amethod of manufacturing an electronic package 2 in accordance with afirst embodiment of the present disclosure. In an embodiment, theelectronic package 2 is manufactured using the Fan-Out Embedded Bridge(FO-EB) technique.

As shown in FIG. 2A, a first electronic component 21 having a conductivelayer 22 on a surface of the first electronic component 21 is provided.The first electronic component 21 is then disposed on a carrierstructure 20 attached to a carrier 9. The carrier structure 20 includesa first side 20 a and a second side 20 b opposite to each other. Thefirst electronic component 21 is disposed on the first side 20 a of thecarrier structure 20. A plurality of conductive pillars 23 (for example,made of a metallic material such as copper or solder material) aredisposed on the first side 20 a of the carrier structure 20. Inaddition, in one aspect, the first electronic component 21 having theconductive layer 22 can first be disposed on the first side 20 a of thecarrier structure 20 before being disposed onto the carrier 9.

In an embodiment, the carrier structure 20 is, for example, a packagesubstrate with a core layer and circuit structure(s), a coreless packagesubstrate with circuit structure(s), a through-silicon interposer (TSI)with through-silicon vias (TSVs), or other types of substrates. Thecarrier structure 20 includes at least one first dielectric layer 200and at least one first circuit layer 201 connected with the firstdielectric layer 200. The first circuit layer 201 is, for example, afan-out redistribution layer (RDL). In one example, the material formingthe first circuit layer 201 is copper, and the material forming thefirst dielectric layer 200 is a dielectric material, such aspolybenzoxazole (PBO), polyimide (PI), or a prepreg (PP). It can beunderstood that the carrier structure 20 can also be other types ofsubstrate for carrying a chip, such as a lead frame, a wafer, and othertypes of boards with metal routings, and the present disclosure is notlimited to the above.

Furthermore, the second side 20 b of the carrier structure 20 isdisposed on the carrier 9 via a plurality of conductive components 29such as solder balls or other metal bumps (e.g., copper pillars). In anexample, the carrier 9 includes a board 90 made of a semiconductormaterial, a dielectric material, a ceramic material, a glass material ora metallic material, but the present disclosure is not limited thereto.The size of the carrier 9 can be chosen as a wafer form substrate or apanel form substrate depending on the needs. A bonding layer 91, such asa release film or an adhesive, can be formed on the board 90 by coatingor bonding. The carrier structure 20 can be laminated onto the bondinglayer 91, and the conductive components 29 are embedded into the bondinglayer 91.

Moreover, the first electronic component 21 is an active component, apassive component or a combination thereof, wherein the active componentis, for example, a semiconductor chip, and a passive component is, forexample, a resistor, a capacitor or an inductor. In an embodiment, thefirst electronic component 21 is a semiconductor chip having an activesurface 21 a, a non-active surface 21 b opposite to the active surface21 a, and side surfaces 21 c adjacent to the active surface 21 a and thenon-active surface 21 b. The first electronic component 21 is disposedon the first side 20 a of the carrier structure 20 via the non-activesurface 21 b of the first electronic component 21, and at least oneelectrode pad 210 (which serves as a power pin port and can be locatedin the center of the active surface 21 a) and a plurality of contacts210 a (which serve as signal pin port and can be located arbitrarily onthe active surface 21 a, such as on the periphery or the center) aredisposed on the active surface 21 a. At least one wire 211 electricallyconnected to the electrode pad 210 and a plurality of integratedcircuits (not shown) electrically connected to the contacts 210 a areprovided inside the first electronic component 21. The wire 211 isexposed from the side surfaces 21 c (as shown in FIG. 2A) or thenon-active surface 21 b (such as a wire 411 shown in FIG. 2E-2) of thefirst electronic component 21. In an example, conductors 212 (in theshapes of pillars, pins or other types of bumps) can be formed on theelectrode pad 210 and the contacts 210 a, and an insulating protectivefilm 213 is formed on the active surface 21 a in such a way that theconductors 212 are exposed from the insulating protective film 213.

In addition, the conductive layer 22 is formed on the non-active surface21 b and the side surfaces 21 c of the first electronic component 21, sothat the first electronic component 21 is disposed on the first side 20a of the carrier structure 20 via the conductive layer 22, and theconductive layer 22 is electrically connected to the first circuit layer201, such that the conductive layer 22 and the wire 211 act as a powertransmission structure. For example, the material forming the conductivelayer 22 can be copper with a plating thickness of about 5 μm. It can beunderstood that when the wire 411 is exposed from the non-active surface21 b of the first electronic component 21, a conductive layer 42 can beformed only on the non-active surface 21 b of the first electroniccomponent 21 (as shown in FIG. 2E-2).

As shown in FIG. 2B, an encapsulant 25 is formed on the first side 20 aof the carrier structure 20, such that the encapsulant 25 covers thefirst electronic component 21, the conductive layer 22 and theconductive pillars 23. Next, a routing structure 26 is formed on theencapsulant 25, such that the routing structure 26 is electricallyconnected with the conductive pillars 23 and the conductors 212.

In an embodiment, the material forming the encapsulant 25 is aninsulating material, such as PI, a dry film, epoxy resin, or a moldingcompound, but the present disclosure is not limited as such. In anexample, the encapsulant 25 can be laminated or molded on the first side20 a of the carrier structure 20.

Furthermore, a planarization process can be performed as needed to allowthe upper surface of the encapsulant 25 to be flush with the end facesof the conductive pillars 23, the surface of the insulating protectivefilm 213 and the top faces of the conductors 212, so that the end facesof the conductive pillars 23, the surface of the insulating protectivefilm 213 and the top faces of the conductors 212 are exposed from theencapsulant 25. For example, the planarization process can be carriedout by polishing to remove part of the conductive pillars 23, part ofthe insulating protective film 213, part of the conductors 212 and partof the encapsulant 25.

Moreover, the routing structure 26 includes a first surface 26 a and asecond surface 26 b opposite to each other. The routing structure 26 isbonded to the encapsulant 25 via the first surface 26 a of the routingstructure 26, such that the first electronic component 21 and theconductive pillars 23 are disposed on the first surface 26 a.

In addition, the routing structure 26 includes at least one seconddielectric layer 260 and a plurality of second circuit layers 261 (e.g.,RDLs) disposed on the second dielectric layer 260. The second circuitlayers 261 of the routing structure 26 are electrically connected to theconductive pillars 23 as well as the electrode pads 210 and the contacts210 a through the conductors 212. In an example, the material formingthe second circuit layer 261 is copper, and the material forming thesecond dielectric layer 260 is a dielectric material, such as PBO, PI,or a PP.

As shown in FIG. 2C, a plurality of second electronic components 24 aredisposed on the second surface 26 b of the routing structure 26, and anencapsulation layer 28 is then formed to encapsulate the secondelectronic components 24.

In an embodiment, the second electronic components 24 are activecomponents, passive components or a combination thereof, and the activecomponents can be, for example, semiconductor chips, and passivecomponents can be, for example, resistors, capacitors or inductors. Inan example, the second electronic components 24 are electricallyconnected to the second circuit layers 261 of the routing structure 26in a flip-chip manner via a plurality of conductive bumps 27 (e.g.,solder bumps, copper bumps, or other types of bumps). As a result, thefirst electronic component 21 becomes a bridge component embedded in theencapsulant 25 and is electrically bridged between adjacent secondelectronic components 24 via the electrode pads 210. However, there arenumerous ways in which the second electronic components 24 can beconnected with the routing structure 26, such as wire bonding, and thepresent disclosure is not limited to the above.

Furthermore, the encapsulation layer 28 can encapsulate the secondelectronic components 24 and the conductive bumps 27 at the same time.Alternatively, an underfill (not shown) can first be formed between thesecond electronic components 24 and the second surface 26 b of therouting structure 26 to cover the conductive bumps 27, and then theencapsulation layer 28 is formed to cover the underfill and the secondelectronic components 24.

Moreover, the encapsulation layer 28 is an insulating material, such asPI, a dry film, or an encapsulant or molding compound such as epoxyresin. The encapsulation layer 28 can be laminated or molded on therouting structure 26. It can be understood that the material forming theencapsulation layer 28 can be the same as or different from that formingthe encapsulant 25.

In addition, the encapsulation layer 28 can cover the backsides (notshown) of the second electronic components 24 or expose the backsides ofthe second electronic components 24 (as shown in FIG. 2C).

As shown in FIG. 2D, the carrier 9 and the bonding layer 91 thereon areremoved to expose the plurality of conductive components 29.

As shown in FIG. 2E-1, a singulation process is performed along cuttingpaths S shown in FIG. 2D to obtain a plurality of electronic packages 2,so that in the subsequent process each of the electronic packages 2 canbe disposed onto an electronic device 7 (e.g., a circuit board) via therespective conductive components 29.

In an embodiment, some of the conductive components 29 of the electronicpackage 2 (e.g., the conductive components 29 shown on the left-handside of FIG. 2E-1) are correspondingly connected to power supply ports70, 71 of the electronic device 7. In an example, the power supply port70 is electrically connected to the conductive layer 22, while the otherpower supply port 71 is electrically connected to the conductive pillar23. It can be understood that other conductive components 29 of theelectronic package 2 (e.g., the conductive components 29 shown on theright-hand side of FIG. 2E-1) are correspondingly connected to signalcontacts (not shown) of the electronic device 7.

Therefore, in the electronic package 2 in accordance with the presentdisclosure, the design of an electrode pad 210, a wire 211, 411 and aconductive layer 22, 42 included in the first electronic component 21allows the electrode pad 210, the wire 211, 411 and the conductive layer22, 42 to serve as a power transmission structure. Thus, compared to theprior art, in addition to the conductive pillars 23 of the electronicpackage 2 of the present disclosure acting as current paths, anadditional current path is formed by the electrode pad 210, the wire211, 411 and the conductive layer 22, 42, thereby reducing the DCresistance of the electronic package 2 and improving the impedance issueassociated with the supply of power.

For example, in the distribution of the contacts 110 in the conventionalfirst semiconductor chip 11 shown in FIG. 1-2, a contact 110 near thecenter (denoted as numeral 24 on the horizontal axis in FIG. 2F-1) has avery large DC resistance (with an impedance value of 38.62 milliohms onan impedance curve L2 in FIG. 2F-1). On the other hand, in thedistribution of pin port of the first electronic component 21 inaccordance with the present disclosure shown in FIG. 2F-2, an electrodepad 210 near the center (denoted as numeral 24 on the horizontal axis inFIG. 2F-1) has a reduced DC resistance (with an impedance value of 17.73milliohms on an impedance curve L1 in FIG. 2F-1), wherein the verticalaxis in FIG. 2F-1 represents impedance in inductor (DCR) generated by aworking voltage (VDD) in a device, and the horizontal axis representsdistribution of pin port on the active surface of a chip (with numeral 1denoting a pin port at the periphery [such as the contact 110, 210 a],and numeral 24 denoting a pin port in the center [such as the contact110 or the electrode pad 210]).

Therefore, as can be seen from FIG. 2F-1, by adding a new power supplyloop (i.e., the current path formed by the electrode pad 210, the wire211, 411 and the conductive layer 22, 42) in the electronic package 2 ofthe present disclosure, the DCR of the FO-EB package can be greatlyreduced (the impedance curve L1 for the electronic package 2 of thepresent disclosure is much lower than the impedance curve L2 of theconventional semiconductor package 1, in other words, by plating thesurface of the first electronic component 21 with a conductive layer 22,42 to a thickness of about 5 μm, the DCR can be reduced by 54%), thepower supply issue of the FO-EB electronic package 2 can be effectivelyaddressed.

Moreover, since the electrode pad 210, the wire 211, 411 and theconductive layer 22, 42 can be used as current path, the manufacturingof the conductive pillars 23 can be omitted depending on power demands(or simply manufacture conductive pillars for other functions not forpower supply use).

In addition, there are numerous processing steps for FO-EB, and thepresent disclosure is not limited to the above. For example, conductivepillars 23 and a first electronic component 21 having a conductive layer22, 42 can first be disposed on a carrier 9, after the processes shownin FIGS. 2B to 2D have been implemented, the carrier 9 is removed beforeforming a carrier structure 20 and conductive components 29.Alternatively, the carrier structure 20 can be omitted and conductivecomponents 29 in electrical connections with the conductive pillars 23and the conductive layer 22, 42 can be directly formed. As such, theelectronic package 2 of the present disclosure can include or omit thecarrier structure 20 depending on the needs.

FIGS. 3A to 3D are schematic cross-sectional views illustrating a methodof manufacturing an electronic module 3 (i.e., the first electroniccomponent 21 with the conductive layer 22) of the electronic package 2in accordance with the present disclosure.

As shown in FIGS. 3A and 3B, a wafer 5 is singulated to obtain aplurality of first electronic components 30. Then, the plurality offirst electronic components 30 are arranged at intervals on a panel formcarrier 8.

In an embodiment, the first electronic component 30 includes an activesurface 30 a and a non-active surface 30 b opposite to each other. Theactive surface 30 a includes a plurality of electrode pads 300 and aplurality of contacts 300 a, and a plurality of wires 301 electricallyconnected with the electrode pads 300 are provided inside the firstelectronic component 30. The first electronic component 30 is attachedonto the carrier 8 via the active surface 30 a. For example, conductors212 are formed on the electrode pads 300 and the contacts 300 a, and aninsulating protective film 213 is formed on the active surface 30 a ofthe wafer 5 to cover the conductors 212, such that the wafer 5 isattached onto the carrier 8 through the insulating protective film 213.

Moreover, after singulation of the wafer 5, the wires 301 are exposedfrom side surfaces 30 c of the first electronic component 30. It can beunderstood that the wires 301 can also be exposed from the non-activesurface 30 b of the first electronic component 30.

As shown in FIG. 3C, a conductive layer 32 is formed on the non-activesurface 30 b and the side surfaces 30 c of the first electroniccomponent 30, such that the conductive layer 32 covers the firstelectronic component 30.

In an embodiment, the conductive layer 32 is coated on the entire or aportion of the non-active surface 30 b and/or the entire or a portion ofthe side surfaces 30 c of the first electronic component 30 byelectroplating, deposition or other methods.

Moreover, the conductive layer 32 is in contact with the wires 301 so asto be electrically connected with the electrode pads 300 via the wires301. The conductive layer 32 is free from being electrically connectedwith the contacts 300 a. For example, the conductive layer 32 and thewires 301 serve as a power transmission structure.

As shown in FIG. 3D, a singulation process is performed along cuttingpaths L shown in FIG. 3C, and then the carrier 8 is removed to obtain aplurality of electronic modules 3, wherein the conductive layer 32 isfree from being formed on the active surface 30 a of the firstelectronic component 30.

In an embodiment, the electronic module 3 is applied to the electronicpackage 2 shown in FIG. 2E-1. Some of the conductive pillars 23 are usedas one power transmission path, and the first electronic component 30provides another power transmission path (i.e., the conductive layer 32,the wire 301 and the electrode pads 300). As such, the first electroniccomponent 30 can be used as a bridge chip between at least two secondelectronic components 24 and provides the power needed by these secondelectronic components 24.

FIGS. 4A and 4B are schematic cross-sectional views depicting anelectronic package 4 in accordance with a second embodiment of thepresent disclosure. The difference between this embodiment and the firstembodiment is in that the electronic package 4 is provided with multiplesets of power transmission structures, and similarities between the twowill not be repeated.

As shown in FIG. 4A, the first electronic component 21 has two sets ofpower transmission structures, which include two wires 211 and 410separate and not connected to each other, so that each of the wires 211and 410 can be electrically connected to a different second electroniccomponent 24. The wires 211 and 410 are electrically connected to afirst conductive layer 22 a and a second conductive layer 22 b,respectively, wherein the first conductive layer 22 a and the secondconductive layer 22 b are formed on the side surfaces 21 c and thenon-active surface 21 b of the first electronic component 21 and areseparate and disconnected from each other.

In an embodiment, the first circuit layer 201 includes a first connector40 a and a second connector 40 b for electrically connecting with thefirst conductive layer 22 a and the second conductive layer 22 b,respectively. In an example, the first and second connectors 40 a and 40b can be in the shape of pads, pillars, or other appropriate shapes, andthe present disclosure is not limited as such.

Moreover, in the two sets of power transmission structures, as shown inFIG. 4B, a wire 411 (electrically connected to a first conductive layer42 a) can be electrically connected to different second electricalcomponents 24 and 44, while another wire 412 (electrically connected toa second conductive layer 42 b) can be electrically connected to asingle second electrical component 44. As such, two sets of powertransmission structures (i.e., the two wires 411 and 412) can bothprovide power required by the same second electrical component 44,wherein the first conductive layer 42 a and the second conductive layer42 b are formed on the non-active surface 21 b of the first electroniccomponent 21, and the first connector 40 a is electrically connected tothe first conductive layer 42 a, while the second connector 40 b iselectrically connected to the second conductive layer 42 b.

Atleast one electrode pad 210 is disposed on the active surface 21 a, andat least one wire 211, 411 electrically connected with the electrode pad210 is provided inside the first electronic component 21.

The conductive layer 22, 42 is embedded in the encapsulant 25 andelectrically connected with the wire 211, 411, wherein the conductivelayer 22, 42 is free from being formed on the electrode pad 210.

In an embodiment, the electrode pad 210 is positioned in the center ofthe active surface 21 a.

In an embodiment, the wire 211, 411 is exposed from the side surfaces 21c and/or the non-active surface 21 b of the first electronic component21 for contacting the conductive layer 22, 42.

In an embodiment, the conductive layer 22, 42 is formed on thenon-active surface 21 b and/or the side surfaces 21 c of the firstelectronic component 21.

In an embodiment, the electronic package 2 further includes a routingstructure 26 formed on the encapsulant 25 and electrically connectedwith the electrode pad 210. For example, the routing structure 26includes a first surface 26 a and a second surface 26 b opposite to eachother, wherein the encapsulant 25 and the first electronic component 21are provided on the first surface 26 a, and at least one secondelectronic component 24, 44 electrically connected with the routingstructure 26 is provided on the second surface 26 b. Furthermore, aplurality of second electronic components 24, 44 are provided on thesecond surface 26 b of the routing structure 26, so that the firstelectronic component 21 is electrically bridged between two of theplurality of second electronic components 24, 44.
